Description

Key Features:

✔ 38kHz Modulated IR Detection – Compatible with 99% of consumer remotes.
✔ Strong Noise Immunity – Built-in AGC (Automatic Gain Control) to reject interference.
✔ Digital Output (Active-Low) – Outputs LOW when IR signal is detected, else HIGH.
✔ Wide Voltage Range (2.5V–5.5V) – Works with 3.3V and 5V logic devices.
✔ Low Power Consumption – Only 0.5mA standby current (ideal for battery projects).
✔ Compact 3-Pin Design – Easy breadboard or PCB integration.
